since been known as the Golgi complex. Recent evidence indicates that 

 a similar structure (see Chapter 4, Figure 4-5) may also occur in certain 

 specialized plant cells (Whaley, ct ciL, 1960). Both the function and 

 reality of the Golgi complex have long been debated. So far as light

microscope studies are concerned, the complex in animal cells can at 

 least be differentiated into two parts: (1) an outer osmiophilic com- 

 ponent, and (2) an inner osmiophobic component. 



In recent years, electron microscopy studies have indicated that the 

 complex has a generalized structural pattern made up of a system of 

 membrane-bound vesicles of varying size, associated with smooth mem-
